I made this work for me by inserting at line 206 of

But I expect this is way too hacky and could never be considered as a

Re: Another Figured Bass problem

[Robert Blackstone]

Hi Harm,

Thank you for this enormous collection of possibilities and code for displaying 
BC-figures.
I may not live long enough to put all of it in practice but for my present 
purpose it is more than sufficient.
On the topic of Figured Bass in LilyPond I still have some other desires, to be 
formulated in a new thread (after I have convinced myself that I won't find it 
somewhere in the documentation) 

Thanks again,

Best regards,

Robert

I looked for a way not to change the input order, but still benefit
from upwards stacking-dir.

Coming up with the code below.
For test-cases I used some of our reg-tests in a modified manner.

figured-bass-continuation-center.ly looks even better, imho.
figured-bass.ly is surely not meant to demonstrate real live input,
though, I add it as well, demonstrating bracketing still works.

\version "2.19.81"

reverseEventChordsElements =
#(define-music-function (mus)(ly:music?)
  (music-map
(lambda (m)
  (if (music-is-of-type? m 'event-chord)
  (let ((ev-chrd-elts (ly:music-property m 'elements)))
(ly:music-set-property! m 'elements
  (reverse
(map
  (lambda (e)
(cond ((and (eq? #t (ly:music-property e 'bracket-start))
(eq? #t (ly:music-property e 'bracket-stop)))
   '())
  ((eq? #t (ly:music-property e 'bracket-start))
   (begin
 (ly:music-set-property! e 'bracket-start '())
 (ly:music-set-property! e 'bracket-stop #t)))
  ((eq? #t (ly:music-property e 'bracket-stop))
   (begin
 (ly:music-set-property! e 'bracket-stop '())
 (ly:music-set-property! e 'bracket-start #t
e)
  ev-chrd-elts)))
m)
  m))
mus))

Hi Torsten,

A nice alternative method, one that requires some extra concentration but works 
well.
Thank you very much.

Re: Another Figured Bass problem

Hi Robert,

How about simply flipping the stacking direction?

   \override BassFigureAlignment.stacking-dir = #UP

That way, the bass figures will be piled up from bottom to top.
Caveat: the first figure entered will be the lowest.


 <<
  { 4 4 4 4 4 4 }
  \figures {
\override BassFigureAlignment.stacking-dir = #UP
<_!> <3+ 6> <4> <4 5> <3+> <_+>
  }
 >>


HTH,
Torsten

Re: Another Figured Bass problem

Hi David,
Thanks for your reaction. 

You write "So blanking entries is done by entering _ instead of a number." 
I'm not sure I fully understand this.
I have tried to get a number, for instance #3 on the second row by entering < _ 
3+ >,  but that didn't change anything; the #3 stayed on the top line.

I used the method just given by Malte Meyn.

Best regards,

Robert Blackstone

Hi Malte,

Many thanks. It is what I needed.

(I think it should be in the Snippet-collection.)

From "Entering figured bass":

Accidentals (including naturals) may be used for modifying scale
steps.  These are entered by appending ‘+’ (for sharps), ‘-’ (for
flats) or ‘!’ (for naturals) after the number.  For double
accidentals the modifier is applied twice.  For the modification of
the third step the number is often omitted, which can be achieved by
using ‘_’ instead of a number.

So blanking entries is done by entering _ instead of a number.

You could use a transparent number:

\version "2.19.81"

space = \markup \tiny \number \transparent 5

<<

  \figures {
<5 4>
